Children of God

Romans 8:14-17 (ESV Strong's)

14 For all who are led by the Spirit of God are sons of God. 15 For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!” 16 The Spirit himself bears witness with our spirit that we are children of God, 17 and if children, then heirs—heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.

If we follow in the footsteps of Christ as led by the Spirit, we will be heirs with Christ and glorified with Him. I’m not sure what exactly happens if we don’t follow in His footsteps, but I don’t want to find out. 

If we are led by the Spirit, we will can be assured we are children of God. The kingdom of heaven belongs to those who become as innocent as a child. The grace of Christ can make that happen.
